PHILADELPHIA (CBS) — A ceremonial lighting at 6:30 p.m. Thursday launches an installation of public art celebrating the 100th birthday of the Ben Franklin Parkway.

The four 26-foot domes at Aviator Park, the Rodin Museum, Park Towne Place and the Spring Garden Triangle are an illuminated art installation to celebrate the Ben Franklin Parkway’s centennial. New media artist Jennifer Steinkamp says her creation was inspired by Franklin’s lightning experiment.

“Small particles of dust crash together and form static electricity and becomes lightning,” Steinkamp said, “and so I decided to make kind of an artistic representation of that process.”
